INTRODUCTION

The following relates to wireless communications and more specificallyto reliability enhancements at a user equipment (UE).

Wireless communications systems are widely deployed to provide varioustypes of communication content such as voice, video, packet data,messaging, broadcast, and so on. These systems may be capable ofsupporting communication with multiple users by sharing the availablesystem resources (e.g., time, frequency, and power). Examples of suchmultiple-access systems include fourth generation (4G) systems such asLong Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, orLTE-A Pro systems, and fifth generation (5G) systems which may bereferred to as New Radio (NR) systems. These systems may employtechnologies such as code division multiple access (CDMA), time divisionmultiple access (TDMA), frequency division multiple access (FDMA),orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonalfrequency division multiplexing (DFT-S-OFDM). A wireless multiple-accesscommunications system may include one or more base stations or one ormore network access nodes, each simultaneously supporting communicationfor multiple communication devices, which may be otherwise known as aUE.

DETAILED DESCRIPTION

In some wireless communication environments, such as in non-terrestrialnetworks (e.g., satellite supported networks), beam switching may occurfrequently relative to other environments (e.g., terrestrial networks).This may be due to beam coverage being relatively small while thesatellites may be moving with a relatively high rate of speed. A networkmay configure a user equipment (UE) with each beam supported by asatellite as well as an initial resource (e.g., bandwidth part) perbeam. As the beam footprints move (or as the UE moves), the network maysignal the UE as to which bandwidth part to utilize. In some cases, awireless communications system may limit the quantity of bandwidth partsthat are configured at a UE. This may be due to the size of a field thatis used to signal a bandwidth part. Because the UE and the network maybe mobile, the limitation of bandwidth parts may affect a UEs ability toefficiently switch between beams.

In some cases, a UE and a satellite may transmit control information ordata messages using one or more beams associated with one or more BWPs.The satellite and the UE may be thousands of kilometers apart and it maytake some time for electromagnetic waves to propagate over the distancebetween the satellite and the UE. The distance that a transmissiontravels may result in substantial signal degradation due to, forexample, atmospheric effects, interference from other radio frequencysources, signal attenuation due to vegetation or structures, and thelike. Further, due to the relatively large round trip delay (RTD)associated with propagation delays (e.g., the amount of time for asignal to travel between a sender and a receiver) between the satelliteand the UE, an inactivity timer associated with a beam may expire. TheUE may use an inactivity timer to determine if one or more BWPs haveexpired (i.e., are no longer active). In some examples, such as when thesatellite is in low earth orbit (e.g., an orbit close to the plant Earthor the area of space below an altitude of 2,000 kilometers (km)), theinactivity timer may expire prior to the UE leaving the coverage of thebeam. However, when the inactivity timer expires, the UE may revert backto one or more default BWPs associated with an outdated beam.Additionally or alternatively, due to the high mobility of the UErelative to the satellite, the UE may frequently switch beams. In somecases, the beam switching operation may fail (e.g., due to loss ofcontrol messages), and the UE may revert back to using an outdated beam,which may cause high signaling volume and inefficient resourceallocation at the UE (e.g., due to cell search operations).

As described herein, a UE may determine a default satellite beam whileconsidering the mobility of the satellite, which may improve theefficiency of beam switching operations in non-terrestrial networks(NTNs) among other benefits. For example, the UE may determine aninactivity timer associated with a beam has expired. In some cases, theUE may identify location information corresponding to the location ofthe UE with respect to the satellite and may transmit the locationinformation to the satellite. The satellite may determine beam geometryinformation for one or more satellite beams or beams (e.g., based on thereceived location information or a current beam), the one or more beamsmay be default beams (e.g., predetermined or preconfigured beams).Additionally or alternatively, the UE may identify the beam geometryinformation, for example, by using a beam identifier, a satelliteidentifier, the location information, or the like. The satellite maytransmit the beam geometry information, which, in one example, may be afunction of time, to the UE. For example, the UE may receive the beamgeometry information from the network entity, or the satellite, during acell search operation.

In some cases, the UE may process the beam geometry information and thelocation information to determine one or more default beams (e.g., adefault beam or a default beam tuple, which may be a pair of beams) thataccounts for the mobility of the satellite relative to the UE. In someexamples, the UE may report the one or more default beams to thesatellite or to the network, and the satellite or the network maytransmit a feedback message confirming the reception of the one or moredefault beams. In some other examples, the satellite (e.g., a networkentity) may determine the one or more default beams based on locationinformation from the UE or based on a current beam (e.g., the currentbeam the satellite is using). The satellite may transmit an indicationof the default beam to the UE.

In some examples, the UE may use the one or more default beams toperform a beam switching operation. For example, the UE may switch toone or more default BWPs associated with default beams. In some cases, adefault BWP may be a BWP the UE reverts back to when an inactivity timerexpires. Otherwise (e.g., if the default satellite beam is a beam tupleor if there are multiple default beams), the UE may transmit ascheduling request to the satellite, may perform a contention freerandom access (CFRA) procedure with the satellite, or may perform acontention based random access (CBRA) procedure with the satellite. Therandom access procedures may involve exchanging signaling (e.g., arandom access preamble during a random access occasion) to establish aconnection.

Aspects of the disclosure are initially described in the context ofwireless communications systems. Additional aspects are described withreference to beam diagrams and a process flow. Aspects of the disclosureare further illustrated by and described with reference to apparatusdiagrams, system diagrams, and flowcharts that relate to default beamfor communication networks.

FIG. 1 illustrates an example of a wireless communications system 100that supports default beam for communication networks in accordance withone or more aspects of the present disclosure. The wirelesscommunications system 100 may include one or more base stations 105, oneor more UEs 115, and a core network 130. In some examples, the wirelesscommunications system 100 may be an LTE network, an LTE-A network, anLTE-A Pro network, or an NR network. In some examples, the wirelesscommunications system 100 may support enhanced broadband communications,ultra-reliable (e.g., mission critical) communications, low latencycommunications, communications with low-cost and low-complexity devices,or any combination thereof.

The base stations 105 may be dispersed throughout a geographic area toform the wireless communications system 100 and may be devices indifferent forms or having different capabilities. The base stations 105and the UEs 115 may wirelessly communicate via one or more communicationlinks 125. Each base station 105 may provide a coverage area 110 overwhich the UEs 115 and the base station 105 may establish one or morecommunication links 125. The coverage area 110 may be an example of ageographic area over which a base station 105 and a UE 115 may supportthe communication of signals according to one or more radio accesstechnologies.

The UEs 115 may be dispersed throughout a coverage area 110 of thewireless communications system 100, and each UE 115 may be stationary,or mobile, or both at different times. The UEs 115 may be devices indifferent forms or having different capabilities. Some example UEs 115are illustrated in FIG. 1. The UEs 115 described herein may be able tocommunicate with various types of devices, such as other UEs 115, thebase stations 105, or network equipment (e.g., core network nodes, relaydevices, integrated access and backhaul (IAB) nodes, or other networkequipment), as shown in FIG. 1.

The base stations 105 may communicate with the core network 130, or withone another, or both. For example, the base stations 105 may interfacewith the core network 130 through one or more backhaul links 160 (e.g.,via an S1, N2, N3, or other interface). The base stations 105 maycommunicate with one another over the backhaul links 160 (e.g., via anX2, Xn, or other interface) either directly (e.g., directly between basestations 105), or indirectly (e.g., via core network 130), or both. Insome examples, the backhaul links 160 may be or include one or morewireless links. A UE 115 may communicate with the core network 130through a communication link 155.

One or more of the base stations 105 described herein may include or maybe referred to by a person having ordinary skill in the art as a basetransceiver station, a radio base station, an access point, a radiotransceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or agiga-NodeB (either of which may be referred to as a gNB), a Home NodeB,a Home eNodeB, or other suitable terminology.

A UE 115 may include or may be referred to as a mobile device, awireless device, a remote device, a handheld device, or a subscriberdevice, or some other suitable terminology, where the “device” may alsobe referred to as a unit, a station, a terminal, or a client, amongother examples. A UE 115 may also include or may be referred to as apersonal electronic device such as a cellular phone, a personal digitalassistant (PDA), a tablet computer, a laptop computer, or a personalcomputer. In some examples, a UE 115 may include or be referred to as awireless local loop (WLL) station, an Internet of Things (IoT) device,an Internet of Everything (IoE) device, or a machine type communications(MTC) device, among other examples, which may be implemented in variousobjects such as appliances, or vehicles, meters, among other examples.

The UEs 115 described herein may be able to communicate with varioustypes of devices, such as other UEs 115 that may sometimes act as relaysas well as the base stations 105 and the network equipment includingmacro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations,among other examples, as shown in FIG. 1.

The UEs 115 and the base stations 105 may wirelessly communicate withone another via one or more communication links 125 over one or morecarriers. The term “carrier” may refer to a set of radio frequencyspectrum resources having a defined physical layer structure forsupporting the communication links 125. For example, a carrier used fora communication link 125 may include a portion of a radio frequencyspectrum band (e.g., a BWP) that is operated according to one or morephysical layer channels for a given radio access technology (e.g., LTE,LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisitionsignaling (e.g., synchronization signals, system information), controlsignaling that coordinates operation for the carrier, user data, orother signaling. The wireless communications system 100 may supportcommunication with a UE 115 using carrier aggregation or multi-carrieroperation. A UE 115 may be configured with multiple downlink componentcarriers and one or more uplink component carriers according to acarrier aggregation configuration. Carrier aggregation may be used withboth frequency division duplexing (FDD) and time division duplexing(TDD) component carriers.

Signal waveforms transmitted over a carrier may be made up of multiplesubcarriers (e.g., using multi-carrier modulation (MCM) techniques suchas orthogonal frequency division multiplexing (OFDM) or discrete Fouriertransform spread OFDM (DFT-S-OFDM)). In a system employing MCMtechniques, a resource element may consist of one symbol period (e.g., aduration of one modulation symbol) and one subcarrier, where the symbolperiod and subcarrier spacing are inversely related. The number of bitscarried by each resource element may depend on the modulation scheme(e.g., the order of the modulation scheme, the coding rate of themodulation scheme, or both). Thus, the more resource elements that a UE115 receives and the higher the order of the modulation scheme, thehigher the data rate may be for the UE 115. A wireless communicationsresource may refer to a combination of a radio frequency spectrumresource, a time resource, and a spatial resource (e.g., spatial layersor beams), and the use of multiple spatial layers may further increasethe data rate or data integrity for communications with a UE 115.

The time intervals for the base stations 105 or the UEs 115 may beexpressed in multiples of a basic time unit which may, for example,refer to a sampling period of T_(s)=1/(Δf_(max)·N_(f)) seconds, whereΔf_(max) may represent the maximum supported subcarrier spacing, andN_(f) may represent the maximum supported discrete Fourier transform(DFT) size. Time intervals of a communications resource may be organizedaccording to radio frames each having a specified duration (e.g., 10milliseconds (ms)). Each radio frame may be identified by a system framenumber (SFN) (e.g., ranging from 0 to 1023).

Each frame may include multiple consecutively numbered subframes orslots, and each subframe or slot may have the same duration. In someexamples, a frame may be divided (e.g., in the time domain) intosubframes, and each subframe may be further divided into a number ofslots. Alternatively, each frame may include a variable number of slots,and the number of slots may depend on subcarrier spacing. Each slot mayinclude a number of symbol periods (e.g., depending on the length of thecyclic prefix prepended to each symbol period). In some wirelesscommunications systems 100, a slot may further be divided into multiplemini-slots containing one or more symbols. Excluding the cyclic prefix,each symbol period may contain one or more (e.g., N_(f)) samplingperiods. The duration of a symbol period may depend on the subcarrierspacing or frequency band of operation.

A subframe, a slot, a mini-slot, or a symbol may be the smallestscheduling unit (e.g., in the time domain) of the wirelesscommunications system 100 and may be referred to as a transmission timeinterval (TTI). In some examples, the TTI duration (e.g., the number ofsymbol periods in a TTI) may be variable. Additionally or alternatively,the smallest scheduling unit of the wireless communications system 100may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

Physical channels may be multiplexed on a carrier according to varioustechniques. A physical control channel and a physical data channel maybe multiplexed on a downlink carrier, for example, using one or more oftime division multiplexing (TDM) techniques, frequency divisionmultiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A controlregion (e.g., a control resource set (CORESET)) for a physical controlchannel may be defined by a number of symbol periods and may extendacross the system bandwidth or a subset of the system bandwidth of thecarrier. One or more control regions (e.g., CORESETs) may be configuredfor a set of the UEs 115. For example, one or more of the UEs 115 maymonitor or search control regions for control information according toone or more search space sets, and each search space set may include oneor multiple control channel candidates in one or more aggregation levelsarranged in a cascaded manner. An aggregation level for a controlchannel candidate may refer to a number of control channel resources(e.g., control channel elements (CCEs)) associated with encodedinformation for a control information format having a given payloadsize. Search space sets may include common search space sets configuredfor sending control information to multiple UEs 115 and UE-specificsearch space sets for sending control information to a specific UE 115.

In some examples, a base station 105 may be movable and thereforeprovide communication coverage for a moving geographic coverage area110. In some examples, different geographic coverage areas 110associated with different technologies may overlap, but the differentgeographic coverage areas 110 may be supported by the same base station105. In other examples, the overlapping geographic coverage areas 110associated with different technologies may be supported by differentbase stations 105. The wireless communications system 100 may include,for example, a heterogeneous network in which different types of thebase stations 105 provide coverage for various geographic coverage areas110 using the same or different radio access technologies.

The wireless communications system 100 may be configured to supportultra-reliable communications or low-latency communications, or variouscombinations thereof. For example, the wireless communications system100 may be configured to support ultra-reliable low-latencycommunications (URLLC) or mission critical communications. The UEs 115may be designed to support ultra-reliable, low-latency, or criticalfunctions (e.g., mission critical functions). Ultra-reliablecommunications may include private communication or group communicationand may be supported by one or more mission critical services such asmission critical push-to-talk (MCPTT), mission critical video (MCVideo),or mission critical data (MCData). Support for mission criticalfunctions may include prioritization of services, and mission criticalservices may be used for public safety or general commercialapplications. The terms ultra-reliable, low-latency, mission critical,and ultra-reliable low-latency may be used interchangeably herein.

In some examples, a UE 115 may also be able to communicate directly withother UEs 115 over a device-to-device (D2D) communication link 135(e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115utilizing D2D communications may be within the geographic coverage area110 of a base station 105. Other UEs 115 in such a group may be outsidethe geographic coverage area 110 of a base station 105 or be otherwiseunable to receive transmissions from a base station 105. In someexamples, groups of the UEs 115 communicating via D2D communications mayutilize a one-to-many (1:M) system in which each UE 115 transmits toevery other UE 115 in the group. In some examples, a base station 105facilitates the scheduling of resources for D2D communications. In othercases, D2D communications are carried out between the UEs 115 withoutthe involvement of a base station 105.

The core network 130 may provide user authentication, accessauthorization, tracking, Internet Protocol (IP) connectivity, and otheraccess, routing, or mobility functions. The core network 130 may be anevolved packet core (EPC) or 5G core (5GC), which may include at leastone control plane entity that manages access and mobility (e.g., amobility management entity (MME), an access and mobility managementfunction (AMF)) and at least one user plane entity that routes packetsor interconnects to external networks (e.g., a serving gateway (S-GW), aPacket Data Network (PDN) gateway (P-GW), or a user plane function(UPF)). The control plane entity may manage non-access stratum (NAS)functions such as mobility, authentication, and bearer management forthe UEs 115 served by the base stations 105 associated with the corenetwork 130. User IP packets may be transferred through the user planeentity, which may provide IP address allocation as well as otherfunctions. The user plane entity may be connected to the networkoperators IP services 150. The operators IP services 150 may includeaccess to the Internet, Intranet(s), an IP Multimedia Subsystem (IMS),or a Packet-Switched Streaming Service.

Some of the network devices, such as a base station 105, may includesubcomponents such as an access network entity 140, which may be anexample of an access node controller (ANC). Each access network entity140 may communicate with the UEs 115 through one or more other accessnetwork transmission entities 145, which may be referred to as radioheads, smart radio heads, or transmission/reception points (TRPs). Eachaccess network transmission entity 145 may include one or more antennapanels. In some configurations, various functions of each access networkentity 140 or base station 105 may be distributed across various networkdevices (e.g., radio heads and ANCs) or consolidated into a singlenetwork device (e.g., a base station 105).

The wireless communications system 100 may operate using one or morefrequency bands, in the range of 300 megahertz (MHz) to 300 gigahertz(GHz). In some cases, the region from 300 MHz to 3 GHz is known as theultra-high frequency (UHF) region or decimeter band because thewavelengths range from approximately one decimeter to one meter inlength. The UHF waves may be blocked or redirected by buildings andenvironmental features, but the waves may penetrate structuressufficiently for a macro cell to provide service to the UEs 115 locatedindoors. The transmission of UHF waves may be associated with smallerantennas and shorter ranges (e.g., less than 100 kilometers) compared totransmission using the smaller frequencies and longer waves of the highfrequency (HF) or very high frequency (VHF) portion of the spectrumbelow 300 MHz.

The electromagnetic spectrum is often subdivided, based onfrequency/wavelength, into various classes, bands, channels, etc. In 5GNR two initial operating bands have been identified as frequency rangedesignations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Thefrequencies between FR1 and FR2 are often referred to as mid-bandfrequencies. Although a portion of FR1 is greater than 6 GHz, FR1 isoften referred to (interchangeably) as a “Sub-6 GHz” band in variousdocuments and articles. A similar nomenclature issue sometimes occurswith regard to FR2, which is often referred to (interchangeably) as a“millimeter wave” band in documents and articles, despite beingdifferent from the extremely high frequency (EHF) band (30 GHz-300 GHz)which is identified by the International Telecommunications Union (ITU)as a “millimeter wave” band.

With the above aspects in mind, unless specifically stated otherwise, itshould be understood that the term “sub-6 GHz” or the like if usedherein may broadly represent frequencies that may be less than 6 GHz,may be within FR1, or may include mid-band frequencies. Further, unlessspecifically stated otherwise, it should be understood that the term“millimeter wave” or the like if used herein may broadly representfrequencies that may include mid-band frequencies, may be within FR2, ormay be within the EHF band.

The wireless communications system 100 may utilize both licensed andunlicensed radio frequency spectrum bands. For example, the wirelesscommunications system 100 may employ License Assisted Access (LAA),LTE-Unlicensed (LTE-U) radio access technology, or NR technology in anunlicensed band such as the 5 GHz industrial, scientific, and medical(ISM) band. When operating in unlicensed radio frequency spectrum bands,devices such as the base stations 105 and the UEs 115 may employ carriersensing for collision detection and avoidance. In some examples,operations in unlicensed bands may be based on a carrier aggregationconfiguration in conjunction with component carriers operating in alicensed band (e.g., LAA). Operations in unlicensed spectrum may includedownlink transmissions, uplink transmissions, P2P transmissions, or D2Dtransmissions, among other examples.

A base station 105 or a UE 115 may be equipped with multiple antennas,which may be used to employ techniques such as transmit diversity,receive diversity, multiple-input multiple-output (MIMO) communications,or beamforming. The antennas of a base station 105 or a UE 115 may belocated within one or more antenna arrays or antenna panels, which maysupport MIMO operations or transmit or receive beamforming. For example,one or more base station antennas or antenna arrays may be co-located atan antenna assembly, such as an antenna tower. In some examples,antennas or antenna arrays associated with a base station 105 may belocated in diverse geographic locations. A base station 105 may have anantenna array with a number of rows and columns of antenna ports thatthe base station 105 may use to support beamforming of communicationswith a UE 115. Likewise, a UE 115 may have one or more antenna arraysthat may support various MIMO or beamforming operations. Additionally oralternatively, an antenna panel may support radio frequency beamformingfor a signal transmitted via an antenna port.

Beamforming, which may also be referred to as spatial filtering,directional transmission, or directional reception, is a signalprocessing technique that may be used at a transmitting device or areceiving device (e.g., a base station 105, a UE 115) to shape or steeran antenna beam (e.g., a transmit beam, a receive beam) along a spatialpath between the transmitting device and the receiving device.Beamforming may be achieved by combining the signals communicated viaantenna elements of an antenna array such that some signals propagatingat particular orientations with respect to an antenna array experienceconstructive interference while others experience destructiveinterference. The adjustment of signals communicated via the antennaelements may include a transmitting device or a receiving deviceapplying amplitude offsets, phase offsets, or both to signals carriedvia the antenna elements associated with the device. The adjustmentsassociated with each of the antenna elements may be defined by abeamforming weight set associated with a particular orientation (e.g.,with respect to the antenna array of the transmitting device orreceiving device, or with respect to some other orientation).

The wireless communications system 100 includes base stations 105, UEs115, satellites 120, and a core network 130. In some examples, thewireless communications system 100 may be an LTE network, an LTE-Anetwork, an LTE-A Pro network, or a NR network. In some cases, wirelesscommunications system 100 may support enhanced broadband communications,ultra-reliable (e.g., mission critical) communications, low latencycommunications, or communications with low-cost and low-complexitydevices.

Wireless communications system 100 may also include one or moresatellites 120. A satellite 120 may communicate with base stations 105(also referred to as gateways in NTNs) and UEs 115 (or other highaltitude or terrestrial communications devices). The satellite 120 maybe any suitable type of communication satellite configured to relaycommunications between different end nodes in a wireless communicationsystem. The satellite 120 may be an example of a space satellite, aballoon, a dirigible, an airplane, a drone, an unmanned aerial vehicle,or the like. In some examples, the satellite 120 may be in ageosynchronous or geostationary earth orbit, a low earth orbit or amedium earth orbit. A satellite 120 may be a multi-beam satelliteconfigured to provide service for multiple service beam coverage areasin a predefined geographical service area. The satellite 120 may be anydistance away from the surface of the earth. A satellite 120 may be ahigh altitude platform station (HAPS), e.g., a balloon.

In some cases, a cell may be provided or established by a satellite 120as part of a non-terrestrial network. A satellite 120 may, in somecases, perform the functions of a base station 105, act as a bent-pipesatellite, or may act as a regenerative satellite, or a combinationthereof. In other cases, satellite 120 may be an example of a smartsatellite, or a satellite with intelligence. For example, a smartsatellite may be configured to perform more functions than aregenerative satellite (e.g., may be configured to perform particularalgorithms beyond those used in regenerative satellites, to bereprogrammed, etc.). A bent-pipe transponder or satellite may beconfigured to receive signals from ground stations and transmit thosesignals to different ground stations. In some cases, a bent-pipetransponder or satellite may amplify signals or shift from uplinkfrequencies to downlink frequencies. A regenerative transponder orsatellite may be configured to relay signals like the bent-pipetransponder or satellite, but may also use on-board processing toperform other functions. Examples of these other functions may includedemodulating a received signal, decoding a received signal, re-encodinga signal to be transmitted, or modulating the signal to be transmitted,or a combination thereof. For example, a bent-pipe satellite (e.g.,satellite 120) may receive a signal from a base station 105 and mayrelay the signal to a UE 115 or base station 105, or vice-versa. Inaccordance with one or more aspects of the present disclosure, a UE 115may communicate with a cell provided or established by a satellite 120(e.g., via a base station 105 or a satellite 120 performing thefunctions of a base station 105) according to an identified default setof one or more beams based on an inactivity timer expiring, which mayenhance communications reliability.

In some cases, a UE 115 and a satellite 120 may transmit controlinformation or data messages using one or more beams associated with oneor more BWPs. The satellite 120 and the UE 115 may be thousands ofkilometers apart and it may take some time for electromagnetic waves topropagate over the distance between the satellite 120 and the UE 115.The distance that a transmission travels may result in substantialsignal degradation due to, for example, atmospheric effects,interference from other radio frequency sources, signal attenuation dueto vegetation or structures, and the like. Further, due to therelatively large RTD associated with propagation delays between thesatellite 120 and the UE 115, an inactivity timer associated with a beammay expire. The UE 115 may use an inactivity timer to determine if oneor more BWPs have expired (i.e., are no longer active). In someexamples, such as when the satellite 120 is in low earth orbit, theinactivity timer may expire prior to the UE 115 leaving the coverage ofthe beam. However, when the inactivity timer expires, the UE 115 mayrevert back to one or more default BWPs associated with an outdatedbeam. Additionally or alternatively, due to the high mobility of the UE115 relative to the satellite 120, the UE 115 may frequently switchbeams. In some cases, the beam switching operation may fail (e.g., dueto loss of control messages), and the UE 115 may revert back to using anoutdated beam, which may cause high signaling volume and inefficientresource allocation at the UE 115 (e.g., due to cell search operations).

In some examples, a UE 115 may determine a default satellite beam whileconsidering the mobility of the satellite 120, which may improve theefficiency of beam switching operations in NTNs among other benefits.For example, the UE 115 may determine an inactivity timer associatedwith a beam has expired. In some cases, the UE 115 may identify locationinformation corresponding to the location of the UE 115 with respect tothe satellite 120 and may transmit the location information to thesatellite 120. The satellite 120 may determine beam geometry informationfor one or more beams (e.g., based on the location information or acurrent beam). In some cases, the satellite 120 may transmit the beamgeometry information to the UE 115. Additionally or alternatively, theUE 115 may identify the beam geometry information, for example, by usinga beam identifier, a satellite identifier, the location information, orthe like to infer the beam geometry information, which may be a functionof time.

In some cases, the UE 115 may process the beam geometry information andthe location information to determine one or more default beams (e.g., adefault beam or a default beam tuple) that accounts for the mobility ofthe satellite 120 relative to the UE 115. In some other cases, thesatellite 120 may use the location information or a current beam todetermine the one or more default beams. The satellite 120 may transmitan indication of the default beams to the UE 115. In some examples, theUE 115 may report the one or more default beams to the satellite 120 orto the network, and the satellite 120 or the network may transmit afeedback message confirming the reception of the one or more defaultbeams. In some examples, the UE 115 may use the one or more defaultbeams to perform a beam switching operation. For example, the UE 115 mayswitch to one or more default BWPs associated with a default beams.Otherwise (e.g., if the default beam is a beam tuple or if there aremultiple default beams), the UE 115 may transmit a scheduling request tothe satellite 120, may perform a CFRA procedure with the satellite 120,or may perform a CBRA procedure with the satellite 120.

FIG. 2 illustrates an example of a wireless communications system 200that supports default satellite beam selection for a communicationnetwork in accordance with one or more aspects of the presentdisclosure. In some examples, wireless communications system 200 mayimplement aspects of wireless communications system 100. Wirelesscommunications system 200 may include a UE 215, a satellite 220, andcommunication links 225, which may be examples of a UE 115, a satellite120, and communication links 125 as described with reference to FIG. 1.In some cases, the satellite 220 may receive a signal from a basestation 105 and may relay the signal to a UE 115 or may perform thefunctions of a base station 105 as described with reference to FIG. 1.The satellite 220 may be referred to as a network entity.

In some wireless communication environments, beam switching may befrequent relative to other environments. In some cases, as illustratedin FIG. 2, a satellite 220 may communicate with a UE 215 via a beam 230,which may be a directional beam. The beam 230 may have a beam footprint235 (e.g., a coverage area of the beam 230). For example, the satellite220 may communicate with the UE 215 via beam 230-a. Additionally oralternatively, the satellite 220 may use beam 230-b or beam 230-c forcommunications. The UE 215 may, in some examples, derive a beamfootprint shape (e.g., hexagonal, circular, elliptical, or the like)based on the shape and structure of the antenna associated with the beam230. In some other examples, the UE 215 may derive a beam size based onone or more power levels associated with the beam 230. The shape andsize of the footprint may depend on the distance of the transmittingdevice (e.g., satellite 220) from the surface of the earth, thetransmitting angle, and the like. Further, footprints that are adjacentmay have different shapes and sizes dependent on the transmission angleand distance of the transmitting device. In some cases, beam footprints235 may overlap. The beam footprint 235 may be small relative to thespeed of a satellite 220. In some other examples, the frequency of beamswitching may depend on the mobility of the UE 215, the mobility of theUE 215 in combination with movement of a base station (e.g., a basestation 105 as described with reference to FIG. 1), or both. Thesatellite may configure each beam 230 from a satellite as a cell with aninitial BWP per beam (e.g., an initial uplink BWP, an initial downlinkBWP, or an uplink BWP and downlink BWP pair). Each pattern of the beamfootprint 235 in FIG. 2 may represent a different initial BWP. In somecases, each beam 230 may be associated with one or more BWPs in additionto the initial BWP, which the UE 215 and the network 220 may use tocommunicate. The network (e.g., satellite 220) may signal to the UE 215which BWP to utilize as the beam footprints 235 move or the UE 215moves.

In some cases, one or more BWPs may be configured for a beam 230 (e.g.,satellite beam) per UE 215. Each beam 230 may be configured with aninitial uplink bandwidth part and an initial downlink bandwidth part.Each beam 230 may also be configured with a default uplink bandwidthpart and a default downlink bandwidth part for a UE 215. Additionalbandwidth parts may be configured per satellite beam. As noted herein,the satellite 220 may configure BWPs in a beam 230 for the UE 215. TheUE 215 may switch BWPs during a BWP switching operation. There may betwo types of BWP switching operations. In inter-beam switching, a UE 215may switch from a BWP in a beam 230 to a BWP in a different beam 230(e.g., from a BWP in beam 230-a to a BWP in beam 230-b). For example, ifthe UE 215 moves from a beam footprint 235 associated with beam 230-a toa beam footprint 235 associated with beam 230-b, the UE may switch froma BWP in beam 230-a to a BWP in beam 230-b. In intra-beam BWP switching,a UE 215 may switch from a BWP to a different BWP in the same beam 230.For example, if the UE 215 performs a BWP switching operation withoutleaving the beam footprint 235 associated with beam 230-a, the UE 215may switch from a BWP associated with beam 230-a to another BWPassociated with beam 230-a. In some examples, the satellite 220 mayconfigure the one or more beams 230 as a single cell. In some otherexamples, the satellite 220 may configure the one or more beams 230 asseparate cells or as multiple cells. That is, each cell may include oneor more beams 230 corresponding to beam footprints 235.

In some examples, the UE 215 may determine a beam 230 to use forcommunication based on monitoring for a broadcast message from thesatellite 220. For example, the satellite 220 may broadcast one or moresynchronization signal blocks (SSBs) to one or more UEs 215. The UE 215may detect an SSB, which may include a master information block (MIB), asystem information block (SIB) (e.g., a first type of SIB (SIB1)), orboth. The UE 215 may decode the MIB to identify one or more parameterswhich may be used to detect and decode the SIB1. For example, the one ormore parameters may include a bandwidth, a control resource set(CORESET), a search space, other parameters related to resourceallocation, or a combination associated with the SIB1. In some examples,the SIB1 may include location information (e.g., a pointer)corresponding to a second type of SIB (SIB2). The SIB2 may include oneor more configurations for BWPs associated with a beam 230 used forcommunication with the satellite 220. Additionally or alternatively, theUE 215 may receive radio resource control (RRC) signaling indicating theone or more configurations for the BWPs associated with the beam 230.

Due to the high mobility of the UE 215 relative to the satellite 220,the UE 215 may frequently switch BWPs associated with one or more beams230. As illustrated in FIG. 2, the UE 215 may traverse seven differentbeam footprints 235, and may perform multiple BWP switching operationsbased on traversing across the beam footprints 235. The beam footprints235 may correspond to a coverage area for a beam relative to the ground.For example, the UE 215 may perform a BWP switching operation to switchfrom BWPs associated with beam 230-a, beam 230-b, or both based on a BWPconfiguration and the trajectory of the UE 215. Additionally oralternatively, the UE 215 may switch to a different cell based ontraversing the beam footprints 235. For example, the beam footprints 235associated with beam 230-a, beam 230-b, and beam 230-c may be associatedwith a first cell, however the other beam footprints 235 may beassociated with different cells. Additionally or alternatively, beamfootprints 235 associated with beam 230-a, beam 230-b, and beam 230-cmay be associated with different cells.

In some cases, the UE 215 may switch beams 230 within a coverage area ofa satellite 220 or when moving from a first coverage area to a secondcoverage area. For example, the UE 215 may move from a beam footprint235 associated with beam 230-a to a beam footprint 235 associated withbeam 230-b. In such examples, the UE 215 may be communicating withsatellite 220 on BWP 2, and may switch from beam 230-a to beam 230-bupon crossing into the beam footprint 235 for beam 230-b. Because of thebeam switch, the UE 215 may also switch from BWP 2 to BWP 1. Similarly,the UE 215 may switch from beam 230-b to another beam 230. The beamswitch may be a result of movement by the UE 215, movement or handoverby a satellite 220, or a combination thereof. In some examples, the UE215 may switch from beam 230-a to beam 230-b based on a beam selectionor beam refinement procedure, or based on detected interference ordegraded signal quality on beam 230-a. In some examples, the BWPs may beseparated by a spectrum gap. The spectrum gap may be used by anothercommunication system, as a guard band, or as another BWP.

In some cases, a BWP switching operation or beam switching operationfrom beam 230-a to beam 230-b may fail (e.g., due to loss of controlmessages), and the UE 215 may revert back to using beam 230-a, which maybe the default beam 230. Thus, one or more default BWPs associated withbeam 230-a may not work anymore because the UE 215 may be out of thecoverage area of beam 230-a, which may cause high signaling volume andinefficient resource allocation at the UE 215 (e.g., due to cell searchoperations). In some examples, a UE 215, a satellite 220, or both maydetermine one or more default satellite beams while considering themobility of the satellite 220 with respect to the UE 215, which mayimprove the efficiency of beam switching operations in NTNs among otherbenefits.

FIG. 3 illustrates an example of a wireless communications system 300that supports default satellite beam selection for a communicationnetwork in accordance with one or more aspects of the presentdisclosure. In some examples, wireless communications system 300 mayimplement aspects of wireless communications system 100 or wirelesscommunications system 200. Wireless communications system 200 mayinclude a UE 315, a satellite 320, and communication links 325, whichmay be examples of a UE 115, a satellite 120, and communication links125 as described with reference to FIG. 1. In some cases, the satellite320 may receive a signal from a base station 105 and may relay thesignal to a UE 115 or may perform the functions of a base station 105 asdescribed with reference to FIG. 1. The satellite 320 may serve acoverage area 310 of a non-terrestrial network (NTN).

In some cases, the coverage area 310 may be a beam footprintcorresponding to one or more beams 330 configured at the satellite 320for communicating with one or more UEs 315. For example, the satellite320 may use multiple antennas to form one or more beams 330 (e.g.,narrow beams) for communication with one or more UEs 315. The beams 330may operate on different frequency intervals (e.g., different BWPs) toreduce interference among the beams 330. That is, beam 330-a may operateusing different BWPs than beam 330-b. In some examples, the satellite320 may configure the one or more beams 330 as a single cell. In someother examples, the satellite 320 may configure the one or more beams asseparate cells.

In some examples, the satellite 320 may communicate with the UE 315 viaone or more communication links 325 using the beam 330. For example, thesatellite 320 may transmit a message to the UE 315 via communicationlink 325-a, which may be used for downlink communications, while the UE315 may transmit a message to the satellite 320 via communication link325-b, which may be used for uplink communications. The satellite 320and the UE 315 may use beam 330-a for both uplink and downlinkcommunications.

The satellite 320 and the UE 315 may be thousands of kilometers apartand it may take some time for electromagnetic waves to propagate overthe distance between the satellite 320 and the UE 315. The propagationdelay for NTNs may be many orders of magnitude larger than thepropagation delay for terrestrial networks. By way of example, thesatellite 320 may be in an orbit, such as low earth orbit, medium earthorbit, other non-geostationary earth orbit, or geostationary earthorbit. In any of these examples, the satellite 320 may be many thousandsof kilometers from earth, and therefore may be thousands of kilometersfrom the UE 315. Each transmission via a communication link 325 betweenthe satellite 320 and the UE 315 (e.g., communication link 325-a,communication link 325-b, or both) may therefore travel from earth thedistance to the satellite 320 and back to earth. The distance that atransmission travels may result in substantial signal degradation dueto, for example, atmospheric effects, interference from other radiofrequency sources, signal attenuation due to vegetation or structures,and the like.

Further, due to the relatively large RTD associated with propagationdelays between the satellite 320 and the UE 315, an inactivity timerassociated with a beam 330 may expire. For example, the satellite 320and the UE 315 may be communicating using beam 330-a, which may beassociated with one or more BWPs. The UE 315 may use an inactivity timerto determine if one or more BWPs have expired (i.e., are no longeractive). The inactivity timer may be a predetermined value (e.g., 2seconds). In some examples, such as when the satellite 320 is in lowearth orbit, the inactivity timer may expire prior to the UE 315 leavingthe coverage of the beam 330. For example, the UE 315 may be in thecoverage area of beam 330-a when the inactivity timer expires, but maymove to the coverage area of beam 330-b soon after. However, when theinactivity timer expires, the UE 315 may revert back to one or moredefault BWPs associated with beam 330-a, which may be outdated.

Additionally or alternatively, due to the high mobility of the UE 315relative to the satellite 320, the UE 315 may frequently switch beams330. For example, the UE 315 may perform a beam switching operation toswitch from beam 330-a to beam 330-b. In some cases, the beam switchingoperation may fail (e.g., due to loss of control messages), and the UE315 may revert back to using beam 330-a, which may be the default beam330. Thus, one or more default BWPs associated with beam 330-a may notwork anymore because the UE 315 may be out of the coverage area of beam330-a, which may cause high signaling volume and inefficient resourceallocation at the UE 315 (e.g., due to cell search operations).

In some examples, a UE 315, a satellite 320, or both may determine oneor more default satellite beams while considering the mobility of thesatellite 320 with respect to the UE 315, which may improve theefficiency of beam switching operations in NTNs among other benefits.For example, the UE 315 may determine an inactivity timer associatedwith beam 330-a has expired. In some cases, the UE 315 may identifylocation information 335 corresponding to the location of the UE 315with respect to the satellite 320. For example, the UE 315 may determinea set of global positioning system (GPS) coordinates corresponding tothe location of the UE 315 and may transmit those coordinates to thesatellite 320. Once the UE 315 transmits the location information 335 tothe satellite 320 via communication link 325-b, the satellite 320 maydetermine beam geometry information 340 for one or more beams 330.Insome cases, the satellite beams in a satellite beam tuple may bereferred to as satellite beams. In some examples, the satellite 320 mayuse the location information 335 to determine the beam geometryinformation 340. In some other examples, the satellite 320 may use acurrent beam 330 (e.g., beam 330-a) to determine the beam geometryinformation 340. In some cases, the satellite 320 may determine one ormore default satellite beams based on the location information 335 orthe current beam 330. The satellite 320 may transmit an indication ofthe default satellite beams to the UE 315. In some cases, the satellite320 may transmit the beam geometry information 340 to the UE 315 viacommunication link 325-a.

Additionally or alternatively, the UE 315 may identify the beam geometryinformation 340 by some other means. For example, the UE 315 may use abeam identifier, a satellite identifier, the location information 335,or the like to determine the beam geometry information 340, which may bea function of time. In some cases, the UE 315 may use a shape and sizeof the coverage area for one or more beams 330, the speed of thecoverage area for one or more beams 330, the direction and angular widthof one or more beams 330, the altitude and speed of the satellite 320,or a combination along with the location information 335 to calculateone or more parameters associated with coverage area 310 or a defaultsatellite beam (e.g., such as beam 330-b).

In some cases, the UE 315 may process the beam geometry information 340and the location information 335 to determine a default satellite beamthat accounts for the mobility of the satellite 320 relative to the UE315, which is described in detail with reference to FIG. 4. In someother cases, the UE 315 may process the beam geometry information 340and the location information 335 to determine a default satellite beamtuple that accounts for the mobility of the satellite 320 relative tothe UE 315, which is described in further detail with reference to FIG.5. In some examples, the UE 315 may report the default satellite beam tothe satellite 320 or to the network, and the satellite 320 or thenetwork may transmit a feedback message (e.g., an acknowledgementmessage (ACK)) confirming the reception of the default satellite beam.

In some examples, the UE 315 may use the default satellite beam toperform a beam switching operation. For example, the UE 315 maydetermine an inactivity timer associated with one or more BWPscorresponding to beam 330-a has expired (e.g., due to a beam switchingfailure or if beam 330-a is outdated). The UE 315 may process thelocation information 335 and the beam geometry information 340 toidentify the default satellite beam, which may be beam 330-b. In somecases, if the default satellite beam is a single beam 330, such as beam330-b, the UE 315 may switch to one or more default BWPs associated withbeam 330-b. Otherwise (e.g., if the default satellite beam is a beamtuple or if there are multiple default satellite beams), the UE 315 maytransmit a scheduling request to the satellite 320, may perform a CFRAprocedure with the satellite 320, or may perform a CBRA procedure withthe satellite 320.

In some cases, the network may allocate one or more time-frequencyresources for a scheduling request on the multiple default satellitebeams. The UE 315 may switch to the default downlink BWP of one of themultiple default satellite beams to monitor a downlink control channel(e.g., a physical downlink control channel (PDCCH)) addressed to the UE315 for a duration. If the UE 315 receives the resource allocation forthe scheduling request via the downlink control channel, the UE 315 maytransmit the scheduling request to the satellite 320 using the defaultsatellite beam. If the UE 315 does not receive the resource allocationfor the scheduling request, the UE 315 may switch to a default downlinkBWP of a different default satellite beam of the multiple defaultsatellite beams to monitor the downlink control channel. In some othercases, the UE 315 may perform a CFRA procedure. For example, the networkmay signal a random access preamble to the UE 315 and a random accessoccasion (e.g., including a time and a frequency). The UE 315 mayperform the CFRA based on the random access preamble and the randomaccess occasion to identify the default satellite beam. In some othercases, the UE 315 may perform a CBRA procedure on the candidate defaultsatellite beams until one is successful.

FIG. 4A and 4B illustrate examples of beam diagrams 400 that supportdefault satellite beam selection for a communication network inaccordance with one or more aspects of the present disclosure. In someexamples, beam diagrams 400 may implement aspects of wirelesscommunications system 100, wireless communications system 200, andwireless communications system 300. For example, beam diagram 400-a mayinclude a UE 415 and beams 405, which may be examples of a UE 115, a UE215, or a UE 315 and beams 230 or beams 330 as described with referenceto FIGS. 1 through 3. In some examples, the UE 415 may communicate witha satellite, such as satellite 120, a satellite 220, or a satellite 320as described with reference to FIGS. 1 through 3, using one of beam405-a through beam 405-g. In some cases, the UE 415 may select one ormore default satellite beams based on the mobility of the UE 415relative to the satellite, which may improve resource allocation andsignaling overhead (e.g., by reducing cell reselection procedures) atthe UE 415.

In some cases, FIG. 4A may illustrate the mobility of a UE 415 acrossthe coverage areas of one or more beams 405 associated with a satellite.For example, the trajectory of the UE 415 may be shown in beam diagram400-a with the coverage areas of the one or more beams 405 as the frameof reference. In some cases, FIG. 4B may illustrate the mobility of theUE 415 across the coverage areas of one or more beams 405 associatedwith a satellite with respect to time. The UE 415 may be in the coveragearea of beam 405-g for a first time interval, T0. The position of the UE415 relative to the coverage areas of the one or more beams 405 maychange over time so that the UE 415 may be in the coverage area of beam405-b during a second time interval, T1, and the UE 415 may be in thecoverage area of beam 405-d during a third time interval, T2. Thus, itmay be beneficial for the UE 415 to select a single default satellitebeam based on the UE trajectory 420. Additionally, the UE 415 mayperform a beam switching operation based on the selected single defaultsatellite beam, which is described in further detail with reference toFIG. 3.

FIG. 5A and 5B illustrate examples of beam diagrams 500 that supportdefault satellite beam selection for a communication network inaccordance with one or more aspects of the present disclosure. In someexamples, beam diagrams 500 may implement aspects of wirelesscommunications system 100, wireless communications system 200, andwireless communications system 300. For example, beam diagram 500-a mayinclude a UE 515 and beams 505, which may be examples of a UE 115, a UE215, a UE 315 and beams 230 or beams 330 as described with reference toFIGS. 1 through 3. In some examples, the UE 515 may communicate with asatellite, such as satellite 120, a satellite 220, or a satellite 320 asdescribed with reference to FIGS. 1 through 3, using one of beam 505-athrough beam 505-g. In some cases, the UE 515 may select a defaultsatellite beam based on the mobility of the UE 515 relative to thesatellite, which may improve resource allocation and signaling overhead(e.g., by reducing cell reselection procedures) at the UE 515.

In some cases, the default satellite beam may be a sequence of satellitebeam tuples, each satellite beam tuple associated with a time intervalduring which the UE 515 is under coverage of that satellite beam tuple.In some cases, FIG. 5A may illustrate the mobility of a UE 515 acrossthe coverage areas of one or more satellite beams 505 associated with asatellite. For example, the trajectory of the UE 515 may be shown inbeam diagram 500-a with the coverage areas of the one or more beams 505as the frame of reference. In some cases, FIG. 5B may illustrate themobility of the UE 515 across the coverage areas of one or more beams505 associated with a satellite with respect to time.

The UE 515 may determine a UE trajectory 520 relative to the coverageareas of the one or more satellite beams 505. In some cases, due to therelative speed of the satellite, the UE trajectory may be fixed. Thus,the UE 515 may identify one or more default satellite beams (e.g., asequence of satellite beams 525) as candidates for a beam switchingoperation. In some cases, the sequence of satellite beams 525 mayinclude satellite beam tuples to account for the uncertainty of the UEtrajectory 520. In some cases, each beam 505 may have a beam identifier,which may correspond to the satellite. The network or the satellite maysend BWP information of one or more default satellite beams to the UE515. The BWP information may associate each beam 505 with an initial BWPpair (e.g., where random access may take place), a default BWP pair(e.g., which may be UE specific), or both. In some cases, the initialuplink BWP and the initial downlink BWP may be the same.

The UE 515 may identify a current location and a speed relative to abeam 505. For example, the UE 515 may be located in the coverage area ofbeam 505-b and may be traversing the sequence of satellite beams 525. Insome cases, the UE 515 may be in the coverage area of beam 505-b, beam505-e, beam 505-c, and beam 505-d for a first time interval, T0. Thus,the default satellite beam during T0 is a beam tuple of satellite beam505-b, beam 505-e, beam 505-c, and beam 505-d, as illustrated in beamdiagram 500-b. The multiple beams 505 account for the uncertainty in theUE trajectory 520. The position of the UE 515 relative to the coverageareas of the one or more beams 505 may change over time so that the UE515 may be in the coverage area of beam 505-c, beam 505-d, and beam505-e during a second time interval, T1, and the UE 515 may be in thecoverage area of beam 505-d during a third time interval, T2. The UE 515may perform a beam switching operation based on the multiple defaultsatellite beams, which is described in further detail with reference toFIG. 3. For example, the UE 515 may transmit a scheduling request, mayperform a CFRA procedure, may perform a CBRA procedure, or a combinationfor the multiple default satellite beams to determine a defaultsatellite beam for the beam switching operation.

FIG. 6 illustrates an example of a process flow 600 that supportsdefault satellite beam selection for a communication network inaccordance with one or more aspects of the present disclosure. In someexamples, process flow 600 may implement aspects of wirelesscommunications system 100, wireless communications system 200, orwireless communications system 300. The process flow 600 may illustratean example of a default satellite beam selection based on mobility of aUE 615 and a satellite 620.

The UE 615 may communicate with the satellite 620via the network entity. At 625, the UE 615 may determine an inactivitytimer associated with a set of one or more beams used for communicatingwith a satellite 620 has expired. In some cases, the satellite 620 mayreceive a signal from a base station 105 and may relay the signal to aUE 615 or may perform the functions of a base station 105 as describedwith reference to FIG. 1. At 630, the UE 615 may identify locationinformation corresponding to the location of the UE 615 with respect tothe satellite 620. In some cases, the location information may be a setof coordinates (e.g., GPS coordinates) corresponding to the location ofthe UE 615.

At 650, the satellite 620 may determine beam geometry information forone or more beams associated with the satellite 620. In some cases, thesatellite 620 may determine the beam geometry information based on anindication of the location information from the UE 615. Additionally oralternatively, the satellite 620 may determine the beam geometryinformation based on the first beam (e.g., the current beam used forcommunicating with the UE 615). In some cases, the beam geometryinformation may include a shape, a size, a velocity, an angular width,or a combination associated with the one or more beams. In some cases,the satellite 620 may calculate one or more parameters associated withthe beam geometry information based on an altitude of the satellite 620,a speed of the satellite 620, a direction of the one or more beams, anangular width of the one or more beams, or a combination.

The beam identifiermay include information associated with the beam geometry informationfor the one or more beams associated with the satellite 620. In somecases, the UE 615 may identify the beam geometry information as afunction of time. In some examples, the beam geometry information may beassociated with the set of one or more beams, which may include one ormore current beams.

At 665, the UE 615 may process the location information from 630 and thebeam geometry information from 660 to identify a second set of one ormore beams, which may include at least one default beam, of the one ormore beams for communicating with the satellite 620. In some cases, theUE 615 may identify the default beam based on the inactivity timerexpiring at 625. In some examples, the second set of one or more beamsmay be different than the first set of one or more beams (e.g., whichmay include the current beam).

At 670, the UE 615 may transmit an indication of the second set of oneor more beams, including the default beam, to the satellite 620. At 675,the satellite 620 may transmit a feedback message based on receiving theindication from the UE 615. In some cases, the feedback message mayinclude an ACK.

At 680, the UE 615 may perform beam switching operation from the firstset of one or more beams (e.g., including one or more current beams) tothe second set of one or more beams (e.g., including one or more defaultbeams). In some cases, the beam switching operation may includeswitching to one or more BWPs associated with the one or more defaultbeams. In some cases, the UE 615 may identify multiple default beams.For example, the second set of one or more beams may include multiplebeam tuples, each beam tuple associated with a time interval duringwhich the UE 615 is communicating with the satellite 620 using the beamtuple. Thus, the UE 615 may transmit a scheduling request to thesatellite 620, may perform a CFRA procedure, or may perform a CBRAprocedure to identify which default beams to use. In some cases, the UE615 may identify one or more resources associated with the one or moredefault beams allocated for a scheduling request. In some cases, the oneor more resources may be allocated by the network or by the satellite620. The UE 615 may monitor a downlink control channel (e.g., a PCCH)using one or more BWPs associated with the one or more default beams forthe one or more resources. The UE 615 may transmit the schedulingrequest to the satellite 620 based on the monitoring (e.g., identifyingthe one or more allocated resources).

In some cases, the UE 615 may receive an indication of a random accesspreamble and a random access occasion from the network or from thesatellite 620. The UE 615 may perform a CFRA procedure based on therandom access preamble and the random access occasion. The UE 615 maydetermine which default beams to use for the beam switching operationbased on the CFRA procedure. In some other cases, the UE 615 may performa CBRA procedure to determine one or more default beam to use for thebeam switching operation. At 685, the UE 615 and the satellite 620 maycommunicate according to the default beams based on performing the beamswitching operation.

In some cases, the beam switching operation may includeswitching to one or more BWPs associated with the one or more defaultbeams. In some cases, the UE 715 may identify multiple default beams.For example, the second set of one or more beams may include multiplebeam tuples, each beam tuple associated with a time interval duringwhich the UE 715 is communicating with the satellite 720 using the beamtuple. Thus, the UE 715 may transmit a scheduling request to thesatellite 720, may perform a CFRA procedure, or may perform a CBRAprocedure to identify which default beams to use. In some cases, the UE715 may identify one or more resources associated with the one or moredefault beams allocated for a scheduling request.
